A sample of tissue can be taken from an organ or any other part of the body by a process called biopsy. The tissue is then sliced into a very thin sections, stained with special dyes, and studied under the microscope to discover abnormalities in the cells.
Radiographs, or X-ray photographs, are used to examine various parts of the body. A chest X ray, for example, can help diagnose tumors, pneumonia, and tuberculosis. X rays can also show bone fractures and other conditions of the musculoskeletal system.
Radiopaque liquids are injected into the urinary tract, spinal column, circulatory system, and other areas. These materials do not allow X rays to pass through them. Thus they allow X-ray examination of soft tissues that would otherwise be invisible by X ray. Spinal cord disorders, for example, often show up in myelograms after a radiopaque liquid has been injected into the spinal canal. Various kinds of angiograms show heart and circulatory disease. In these procedures a radiopaque dye is injected into a vein or artery, X-ray photographs will then show if there is a blockage or an aneurysm.
